<span>Condensation is the process of water vapour turning into liquid, if this stage does not occur, there is no rain. Over time lakes and rivers dry up the Earth would most likely be a desert and water would become scarce. After the evapouration process takes a certain amount of water then plants and animals will die off. The water cycle especially the condensation portion is vital to our and the planets survival.
